Hello Satfyro,
I’m sorry to hear about the rejections you’ve faced, but please know that it's a common experience in the gaming industry. Since you’re under 18, you’ve got plenty of time to continue developing your craft and gaining recognition. Starting so early will give you a great head start in the future! And keep in mind that a lot of the rejections you’ve faced might be because many projects require 18+ team members.
As someone nearly twice your age, I can’t promise the rejections will one day stop, especially in the entertainment industry, but keep building up your portfolio and searching for projects that are the right fit. Eventually, I’m sure you’ll land a role that matches your talents.
That being said, I’m not currently looking for a 3D artist for this jam project, and I may not need one at all. Please don’t take this as another rejection, my original post might not have been as clear as I hoped in explaning this, but I’m looking for a Game Designer with strong programming skills to work alongside me in Unity.
Best of luck in all your endeavors!
